Strongheart halflings are a subrace of halflings with a strong drive to compete and many oppurtunities to practice their skills. However, they have not experienced the same kind of adversity that the common lightfoot halflings have survived.

Compared with other halfling subraces, the stronghearts are a more organized, orderly, and industrious race. They build to last, and fiercely defend their homelands against threats that other halfling subraces would simply flee. Some are surprised to learn that some halflings are capable of a warrior tradition and aren't afraid to show a hint of arrogance or confidence in their own abilities and strengths. Strongheart halflings enjoy athletic contests and value exceptional skills of all kinds.
